Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-2, a disposable atomized injection drug delivery device comprises an outer shell 1 made of transparent plastic material and provided with a scale on the surface thereof, a plunger push rod 2 with one end extending to the left side of the outer shell is movably sleeved in the outer shell 1, a piston is arranged at the other end of the plunger push rod 2 and is in friction contact with the inner wall of the outer shell 1, an atomized spray head 3 is fixedly arranged on the right side of the outer shell 1, a plurality of groups of guide grooves 10 which are arranged in an annular array are arranged in the atomized spray head 3 and are communicated with the left side and the right side of the atomized spray head 3, an inner groove 12 is formed in the atomized spray head 3 and is communicated with the inside of the guide grooves 10, an elastic stop 13 which can be radially contracted is movably connected in the inner groove 12, a clamping ring 4 is fixedly arranged on the left side of the inside of the atomized spray head 3, one end of the needle tube 5 extending to the inside of the plunger push rod 2 is clamped through the clamping ring 4, a guide hole 14 which is communicated to the inner cavity of the plunger push rod 2 is formed on one side of the outer surface of the plunger push rod 2 as shown in fig. 4, and then negative pressure is formed in the inner cavity of the outer shell 1 in the process of pulling the plunger push rod 2 to move leftwards.
As shown in fig. 3-4, in the present technical solution, the left side of the outer surface of the needle tube 5 is provided with an inner gasket 9, and is in frictional contact with the inner wall of the inner chamber 7 formed in the interior of the plunger rod 2, so that in the process of moving the plunger rod 2 to the left side, the volume on the right side of the inner chamber 7 can be compressed, and a high pressure state is formed in the interior of the inner chamber to provide power support for the shrinkage action of the needle tube 5, and the left side of the interior of the plunger rod 2 is provided with a set of ventilation holes communicated to the inner chamber 7, so that in the process of moving the plunger rod 2 to the left side, the gas pressure in the left side of the inner chamber 7 is balanced.
As shown in fig. 1 and fig. 4, in the present technical solution, a limit groove 8 is formed on the right side of the outer surface of the needle tube 5, and is clamped with a snap ring 4 fixedly installed in the inner cavity of the atomizer 3, so that the connection strength between the needle tube 5 and the atomizer 3 can be effectively increased, and when the needle tube 5 is used for extracting the medicament in the xilin bottle, the tip of the needle tube is not easy to automatically shrink under stress.
In the technical scheme, the connection strength of the clamping ring 4 on the atomizing nozzle 3 to the needle tube 4 is set according to the injection capacity of the outer shell 1, and is always larger than the destructive force generated by the needle tube 5 to the clamping ring 4 when the plunger push rod 2 on the atomizing nozzle moves to the leftmost side and the pressure in the right side of the inner cavity 7 is always larger than the destructive force generated by the needle tube 5 to the needle tube 4 when the outer shell 1 on the drug feeder extracts the maximum capacity of the drug, so that the needle tube 5 in the drug feeder is ensured not to suddenly shrink in the process of extracting the drug; and in the process that the drug dispenser extracts the maximum volume of the drug and continuously moves to the left side, the connection between the clamping ring 4 and the needle tube 5 can be broken, and then the needle tube 5 can be automatically contracted under the pressure action of the right side of the inner cavity 7.
In this technical scheme, the middle part of elasticity dog 13 on atomizer 3 inserts needle tubing 5 and is the state of inflation to the intercommunication of guiding gutter 10 is blocked, in order to ensure that this medicine feeder can be used for drawing the medicament totally to the negative pressure that produces when plunger push rod 2 moves left side, and when the needle tubing 5 in elasticity dog 13 withdraws and does not contact with the inside of elasticity dog 13, elasticity dog 13 radially inwards takes place shrink and communicates guiding gutter 10, and then forces the medicament to spray along the passageway atomizing of guiding gutter 10.
In this technical scheme, one side of atomizer 3 surface is equipped with a plurality of groups of intercommunicating pore 11 that are linked together with guiding gutter 10 for the medicament in this medicine feeder is umbrella form and atomizes and spray out, and then has effectively improved this medicine feeder to the atomizing of medicament and spray coverage.
In this technical scheme, the surface of plunger push rod 2 is equipped with a plurality of groups and is annular array arrangement baffle, and the outside of baffle and the inner wall friction contact of shell body 1 to at the in-process that plunger push rod 2 left and right sides removed, but wherein the coincidence of keeping the height between axis and the axis of shell body 1, and then effectively reduced the wearing and tearing that cause on it the piston.
In the technical scheme, the right end of the outer shell 1 is provided with an end cap 6 which is spread outwards, and is used for supporting the oral cavity of a patient when the medicament is sprayed to the laryngeal chamber and the trachea of the patient.
The application method and the working principle of the embodiment are as follows:
when the drug feeder is needed to be used, firstly, the tip of the needle tube 5 stretches into a drug and the plunger push rod 2 is moved to the left side, so that negative pressure is generated on the right side of the inner cavity of the outer shell 1, the drug is extracted into the inner cavity of the outer shell 1 through the drainage hole 14 on the needle tube 5, and meanwhile, the volume on the right side of the inner cavity 7 is gradually reduced and the pressure is gradually increased along with the movement of the plunger push rod 2 to the left side;
after the medicament is extracted, the plunger push rod 2 is continuously moved to the left, so that the pressure on the right side of the inner cavity 7 is increased to a certain degree, and the pressure on the left side with certain strength is applied to the needle tube 5, so that the clamping between the limit groove 8 on the needle tube 5 and the clamping ring 4 on the atomizing nozzle 3 is damaged, and the needle tube 5 automatically contracts into the inner cavity of the plunger push rod 2 under the action of the pressure on the right side of the inner cavity 7 and is not contacted with the inner part of the elastic stop block 13;
and then the elastic stop 13 is contracted and communicated with the diversion trench 10 along the radial inward side, and in the process of moving the plunger push rod 2 to the right side, the medicament in the elastic stop is atomized and sprayed to the laryngeal chamber and the trachea of a patient through the diversion trench 10 under the action of pressure, so that the uniform atomization spraying operation of the medicament is realized.
